摘要
为探索干旱内陆河流域降水稀少、生态环境脆弱、人类长期活动和剧烈气候变化等对流域内水循环产生的影响,以玛纳斯河流域为例,根据天然-人工二元水循环系统理论,建立了二元水循环模型,并对该流域水循环每一环节的蒸发、渗漏进行了计算。结果表明:玛纳斯河流域平原区天然水循环通量为9.38亿m3/a,占流域降水通量的11.70%;人工水循环通量为18.35亿m3/a,占流域降水通量的22.88%;平原区的人工水循环通量已经远远超过了天然水循环通量。玛纳斯河流域总水循环通量为80.26亿m3/a,现状条件下全流域天然水循环通量为61.91亿m3/a,流域天然水循环通量与人工水循环通量的比例为77.14∶22.86。
A water cycle model with two factors is established based on Natural-Artificial water system theory with two factors in Manas River Basin to explore the scarce rainfall,fragile ecological environment and severe long-term human activity and climate change impact of convection within the water cycle in arid inland river basin.Every aspect of the water cycle of evaporation and seepage was calculated.The results show that natural water cycle flux is 938 million m^3/a and proportion of the total is 11.70%.While artificial water cycle flux is 1.835 billion m^3/a and proportion of the total is 22.88% in Manas River plain.The artificial water cycle fluxes are far exceeding the natural water cycle flux in plain area.The total flux of the Manas River basin is 8 026million m^3/a.Natural water cycle flux is 6.191 billion m^3/a Currently.The ratio of basin natural and artificial water cycle water cycle flux is 77.14:22.86.
